Abstract: A power adapter with a power saving mode includes a power adaptation unit. The power adaptation unit includes a pulse width modulation control unit and a power saving signal receiver. The power saving signal receiver is electrically connected to the pulse width modulation control unit. When the power adapter enters a working status, the power adapter charges a battery. After the power saving signal receiver receives a battery fully-charged signal, the power adapter enters a sleeping status.

Abstract: A power conversion system with clamp mode switching includes a clamp conversion circuit, a switching circuit module, a PWM control module, and a feedback control module. The PWM control module stabilizes a feedback voltage when the feedback control module feeds the feedback voltage back to the switching circuit module and the PWM control module. The switching circuit module switches the clamp conversion circuit to operate in an active clamp mode or a non-active clamp mode.
